In Ubuntu 10.04 Evince does not display comments in an annotated PDF file. Or at least that is what my experience is when I was trying to view them. I searched for information about it and I found some people who complained about this feature missing.

I am wondering if anyone has suggestions for a good PDF viewer that run in gnome and displays comments in an annotated PDF file. I don't care about being to annotate the file myself right now, I just want to be able to view comments made by someone else.

To view comments in PDF files under linux you may consider using current version of Firefox. Just drag PDF file into browser window or put absolute path to given file in the location bar (ie. /home/username/Documents/file.pdf) and hit Enter.

If you are using older version of Firefox it's possible that this feature is disabled by default (since it sometimes caused problems; howtogeek.com has an article that describes how to enable it). You may also install it as addon from:

I think that you got voted down because Adobe Reader is available as a native application and it does let you view comments. Admittedly it is not an open source application though.
